I don't know if I'm looking too much into Atty's face, but I feel the look he has is more, "I have faith in my Pokemon's ability." instead of him just being stubborn to George's advice and the words of the viewers.

@Kitleena: While i don't actually have an answer, one guess of mine is that Psyduck's constant headache doesn't allow it to swim, so after it's headache goes away once it evolves, it turns blue to blend into the water. There, hows that for scientific. XD

Favorite speech bubble: How much more punishment can that thing take?!

@Kitleena: Well, to answer that, you have to know that Golduck's name doesn't change in Japanese, but Psyduck does. It is "Koduck", which means "child duck". Golduck may indeed come from "gold" and "duck". This is because gold as a color is often used to symbolize the Psychic type. Abra's line, the Marshe badge being the Gold Badge, etc.

My predictionAtty is allowed to use three Pokemon. Dragonthing is obviously his first, and is going to get crushed. The logical next choice is Rat. But Atty is going to think "maybe the fish will do better in water", and throw poor Fish to its doom. Next, he'll use Oddish. It has a type advantage, but he hasn't trained it at all, so it gets crushed as well. And in the end, Rat, the Pokemon that could have saved Atty in this fight, is the only one he won't use (aside from the one he apparently stole that we haven't seen yet, I guess).

Psychic!Okay I got it this time:
Atty calls DT back, and it's a nice, heartwarming strategy session they have on the sideline.
Meanwhile,
Atty sends in Fish, who after getting tossed around evolves mid-battle as can only happen outside the games, thereby spoiling DT's triumphant return to battle.
And when Super Fish rampages, Rat saves them all. Butthen the squirtle squad busts in. And Atty and George leave town.
And later, when Atty becomes champion, oddish is still dances.
The End. B- good effort

Leave it to Mokepon to poke fun at my inability to remember that Golduck is indeed NOT a psychic-type! I've been at this series for HOW LONG now? And I still can't remember what types are good against what, and that a Golduck is a solid water-type.
